CORN-PLANTER.

SPECIFICATION formingpart of Letters Patent No. 250,748, dated December13, 1881. Application filed October .28, 1880. '(No model.)

- the following is a full description, reference being had to theaccompanying drawings, in which Figure 1 is a side elevation, with aportion of the frame-work in section Fig. 2, a top or plan view, showingone side of a planter with its seed-box and other devices; Fig. 3, aside elevation showing the lever in position to advance the shaft; Fig.4, a side elevation showing the lever when it has completed its strokeand advanced the shaft.

This invention relates to that class of cornplanters in which theseed-dropping mechanisni is actuated through the medium of areciprocating bar which is operated by means of a lever operated from acrank-wheel through the rotation of a shaft, the shaft being given anintermittent revolution through a lever which engages with a wire orcord stretched across the field; and it has for its object thesimultaneous stopping of the wheel which operates or drives theintermittentl y-revolvin g shaft when the lever which advances thiswheel has completed its'stroke and advanced or rotated the shaft asufficient distance to operate the reciprocating bar of the seedingdevices; and its nature consists in providing a slide or stop arrangedto be operated in unison with the movement of the cord-lever, andlocated so that when advanced its point will be in position to engagewith a tooth of the actuating-wheel and stop the movement thereof.

Only the forward or runner portion of a com plete planter is shown inthe drawings.

In the drawings, A represents the check- .cord lever; B, the toothedwheel for drivin g the shaft; G, the latch or pawl for engaging andadvancing the wheel B; D, the sliding stop; E, the groove in which thestop moves; F, the support for the stop; G, the standard or postsupporting the lever, shaft, and other devices; H, a cross-piece forminga guide for the cord-lever; I, the shaft; J, the pulleywheel; K, thecrank-wheel L L, thelever for operating the reciprocating bar; M, therecipslide or stop.

The cordlever A, with its slot at, is made in any of the usual formsofconstruction for such levers. As shown, it is pivoted or mountedloosely on the end of the main shaft I, and its upper end is slotted toreceive the cord or wire and be engaged by the knots thereon.

The wheel B is firmly secured to the shaft I by keying or in some othersuitable manner, so that when revolved it will communicate motion to theshaft. The periphery of this wheel is provided with teeth or lugs b, oneface of each lug being straight or tangential, or nearly so, and theother face being inclined or curved.

The latch or pawl C is of the usual construction, pivoted to the leverA, so that its free end will engage the straight face of the teeth orlugs I), and is held in engagement therewith by means of a spring, 0.

The stop D is located in a suitable groove, E, formed in the side of thesupport F near its outer end, the support at its other end being securedin a firm manner to the upright or standard G. This stop or slide D isset at an incline, and is so arranged that its inner end, when advanced,will approach the wheel B, so as to be nearly in contact with itsperiphery, so that the inclined face of the teeth I) will strike againstthe end of the slide, which acts as a stop to prevent further movementof the wheel until the slide is withdrawn, the end of the slide beingbeveled, so as to be properly engaged by the face of b. This slide D isconnected by a link or rod, d, to the lower end of the lever, one end ofthe link being pivoted in the lever and the other attached by an eye orin some other suitable manner to the slide or stop, and the length ofthis rod and its connections with the lever and slide are such that asthe lever is advanced by the action of the cord the slide will beadvanced in unison, and so IOU that when the stroke of the lever iscompleted the slide will be advanced to be engaged by the face of theteeth I), which stops the movement of the wheel B simultaneously withthe completion of the forward stroke of the lever.

As shown, the spring 0 is secured at one end to the bar or support F,and its other end is attached to the slide D, so that when the stop D isadvanced the spring 6 will be contracted, and when the cord-knot passesfrom the lever A the recoil ot the spring will return the lever B andthe slide or stop D to their normal condition, to be again advanced tooperate and stop the wheel B. Other devices than the form of springshown can be used for returning the slide or stop D and lever A.

The parts represented by the letters G H I JK L M NO PQ R maybeof'anyofthe well-known forms of construction for such parts in thatclass of corn-planters in which the seeding mechanism is operatedthrough a reciprocating bar, an L-lever, a crank-wheel, a pulley, and arevolving shaft, having an intermittent in ovement given thereto by theadvance of the cord-lever, and such parts are therefore not specificallydescribed, as they are constructed, arranged, and operated as usual.

By means of the slide or stop D, connected with and operated from thecord-lever, it will be seen that the movement of this slide mustcorrespond with that of. the lever, and that by arranging the slide sothat when its forward movement ceases it will be at the proper point toreceive the inclined face of the wheel lug or tooth a sure and effectivestop is provided for the wheel, which will always act when the lever isoperated.

nected with the lever, and adapted to advance toward the toothed wheelin unison with the advance movement of the lever, and to engage thetoothed wheel for stopping its rotation simultaneously with thecompletion of the advance movement of the lever, substantially asdescribed.

3. The combination, with the lever A, operated by the check-rod, thetoothed wheel B, and the pawl O, of a movable stop, a link-connectionbetween the stop and the lever, and a retractile spring connected withthe stop,

. whereby the latteris moved in unison with the lever to engage thetoothed wheel and simultaneously stop the advance movement of the samewith the completion of the advance movement of the lever, substantiallyas described.
